PCI: rcar-host: Remove unused static pcie_base and pcie_dev

Browse Source 
After the L1 link state transition exception handler rework, the static
copies of the remapped PCIe controller address and the PCIe device
pointer became unused.  Remove them.

Fixes: 6e36203bc1 ("PCI: rcar: Use PCI_SET_ERROR_RESPONSE after read which triggered an exception")
